26 ##### How to use this driver #####
27 ==============================================================================
28 [..]
29 (#)Declare a HCD_HandleTypeDef handle structure, for example:
30 HCD_HandleTypeDef hhcd;
31
32 (#)Fill parameters of Init structure in HCD handle
33
34 (#)Call HAL_HCD_Init() API to initialize the HCD peripheral (Core, Host core, ...)
35
36 (#)Initialize the HCD low level resources through the HAL_HCD_MspInit() API:
37 (##) Enable the HCD/USB Low Level interface clock using the following macros
38 (+++) __HAL_RCC_USB_OTG_FS_CLK_ENABLE();
39 (+++) __HAL_RCC_USB_OTG_HS_CLK_ENABLE(); (For High Speed Mode)
40 (+++) __HAL_RCC_USB_OTG_HS_ULPI_CLK_ENABLE(); (For High Speed Mode)
41
42 (##) Initialize the related GPIO clocks
43 (##) Configure HCD pin-out
44 (##) Configure HCD NVIC interrupt
45
46 (#)Associate the Upper USB Host stack to the HAL HCD Driver:
47 (##) hhcd.pData = phost;
48
49 (#)Enable HCD transmission and reception:
50 (##) HAL_HCD_Start();
